I've never understood the "complexity" of PGP/GNuPG. Granted the man page is dozens of pages long, but I find it no more complicated than any other command line tool. Maybe it is because I have used it professionally and personally forever. The author of Age has ported Pass to use Age as the encryption scheme if one needs a modern solution. As for reading the directory structure, you don't have to put your passwords…
The agent-driven nature of PGP, along with the encoding itself (which was primarily meant for emails) adds a lot of complexity, and makes it much harder to setup, configure, and use safely compared to other tools. It is a tool trying to securely manage keys in an insecure environment, and even offloading some parts (such as to a yubikey) doesn't make it any easier to use.
Genuinely curious as to what other tools. I don't find PGP terribly too complex to setup or manage.

I mean, yea. Isn't that every encryption tool on someone's local machine?
